Description

The STEVAL-CCA042V1 demonstration board is

designed for the TDA7491HV high-power dual

BTL class-D audio amplifier.

Thanks to its high efficiency, the device

assembled in the PSSO36 (slug-down) package

is capable of dissipating heat without a heatsink.

Jumpers on the board allow configuration of the

amplifier to verify all the features as single-ended

or differential inputs, fixed gain settings.

Microswitches are also provided to enable the

standby and mute functions
